Other secondary scoliosis, cervicothoracic region

This code signifies a curvature of the spine in the neck and upper back (cervicothoracic region) that is not idiopathic but rather a consequence of another underlying condition. This secondary scoliosis can result from various factors such as neuromuscular disorders, congenital anomalies, or trauma.

Apply this code when documentation clearly indicates scoliosis in the cervicothoracic region that is secondary to another disease or condition, rather than being of unknown origin. Supporting documentation should identify the underlying cause of the spinal curvature.

• Ensure the documentation specifies the cervicothoracic region; otherwise, a more general code for secondary scoliosis may be appropriate.
• Always code the underlying primary condition causing the secondary scoliosis first, followed by this code.
• Distinguish carefully from idiopathic scoliosis (M41.1-) and neuromuscular scoliosis (M41.4-), which have their own specific codes.
